| 2 | The rice OsV4 encoding a novel pentatricopeptide repeat protein is required for chloroplast development during the early leaf stage under cold stress显示文摘Pentatricopeptide repeat(PPR)proteins,characterized by tandem arrays of a 35 amino acid motif,have been suggested to play central and broad roles in modulating the expression of organelle genes in plants.However,the molecular mechanisms of most rice PPR genes remains unclear.In this paper,we isolated and characterized a temperature-conditional virescent mutant,OsV4,in rice(Oryza sativa cultivar Jiahua1(WT,japonica rice variety)).The mutant displays albino phenotype and abnormal chloroplasts at the three leaf stage,which gradually turns green after the four leaf stage at a low temperature(20°C).But the mutant always develops green leaves and well-developed chloroplasts at a high temperature(32°C).Genetic and molecular analyses uncovered that OsV4 encodes a novel chloroplast-targeted PPR protein including four PPR motifs.Further investigations show that the mutant phenotype is associated with changes in chlorophyll content and chloroplast development.The OsV4transcripts only accumulate to high levels in young leaves,indicating that its expression is tissue-specific.In addition,transcript levels of some ribosomal components and plastid-encoded polymerase-dependent genes are dramatically reduced in the albino mutants grown at 20°C.These findings suggest that OsV4 plays an important role during early chloroplast development under cold stress in rice. | Xiaodi Gong Qianqian Su Dongzhi Lin Quan Jiang Jianlong Xu Jianhui Zhang Sheng Teng Yanjun Dong | 2014 | Journal of Integrative Plant Biology2014，56，4： | 19 |
| 3 | Roles of manganese oxides in degradation of phenol under UV-Vis irradiation:Adsorption,oxidation,and photocatalysis显示文摘Manganese oxides are known as one type of semiconductors,but their photocatalysis characteristics have not been deeply explored.In this study,photocatalytic degradation of phenol using several synthesized manganese oxides,i.e,acidic birnessite (BIR-H),alkaline birnessite (BIR-OH),cryptomelane (CRY) and todorokite (TOD),were comparatively investigated.To elucidate phenol degradation mechanisms,X-ray diffraction (XRD),ICP-AES (inductively coupled plasma-atomic emission spectroscopy),TEM (transmission electronic microscope),N 2 physisorption at 77 K and UV-visible diffuse reflectance spectroscopy (UV-Vis DRS) were employed to characterize the structural,compositional,morphological,specific surface area and optical absorption properties of the manganese oxides.After 12 hr of UV-Vis irradiation,the total organic carbon (TOC) removal rate reached 62.1%,43.1%,25.4%,and 22.5% for cryptomelane,acidic birnessite,todorokite and alkaline birnessite,respectively.Compared to the reactions in the dark condition,UV- Vis exposure improved the TOC removal rates by 55.8%,31.9%,23.4% and 17.9%.This suggests a weak ability of manganese oxides to degrade phenol in the dark condition,while UV-Vis light irradiation could significantly enhance phenol degradation.The manganese minerals exhibited photocatalytic activities in the order of:CRY > BIR-H > TOD > BIR-OH.There may be three possible mechanisms for photochemical degradation:(1) direct photolysis of phenol;(2) direct oxidation of phenol by manganese oxides;(3) photocatalytic oxidation of phenol by manganese oxides.Photocatalytic oxidation of phenol appeared to be the dominant mechanism. | Qin Zhang Xiaodi Cheng Chen Zheng Xionghan Feng Guohong Qiu Wenfeng Tan Fan Liu | 2011 | Journal of Environmental Sciences2011，23，11： | 11 |
| 4 | DDIT4 promotes gastric cancer proliferation and tumorigenesis through the p53 and MAPK pathways显示文摘Background:Gastric cancer(GC)is one of the most common malignancies worldwide,particularly in China.DNA damage-inducible transcript 4(DDIT4)is a mammalian target of rapamycin inhibitor and is induced by various cellular stresses;however,its critical role in GC remains poorly understood.The present study aimed to investigate the poten-tial relationship and the underlying mechanism between DDIT4 and GC development.Methods:We used western blotting,real-time polymerase chain reaction,and immunohistochemical or immunoflu-orescence to determine DDIT4 expression in GC cells and tissues.High-content screening,cell counting kit-8 assays,colony formation,and in vivo tumorigenesis assays were performed to evaluate cell proliferation.Flow cytometry was used to investigate cell apoptosis and cell cycle distribution.Results:DDIT4 was upregulated in GC cells and tissue.Furthermore,downregulating DDIT4 in GC cells inhibited proliferation both in vitro and in vivo and increased 5-fluorouracil-induced apoptosis and cell cycle arrest.In contrast,ectopic expression of DDIT4 in normal gastric epithelial cells promoted proliferation and attenuated chemosensitivity.Further analysis indicated that the mitogen-activated protein kinase and p53 signaling pathways were involved in the suppression of proliferation,and increased chemosensitivity upon DDIT4 downregulation.Conclusion:DDIT4 promotes GC proliferation and tumorigenesis,providing new insights into the role of DDIT4 in the tumorigenesis of human GC. | Feng Du Lina Sun Yi Chu Tingyu Li Chao Lei Xin Wang Mingzuo Jiang Yali Min Yuanyuan Lu Xiaodi Zhao Yongzhan Nie Daiming Fan | 2018 | Cancer Communications2018，38，1： | 10 |
| 5 | Red and Blue Lights Significantly Affect Photosynthetic Properties and Ultrastructure of Mesophyll Cells in Senescing Grape Leaves显示文摘Light quality significantly affects photosynthetic efficiency in plants. The mechanisms for how light quality affects photosynthesis in grape is poorly understood. Therefore, to investigate the effects of different light qualities on chloroplast ultrastructure and photosynthesis efficiency, two grape cultivars ‘Italia'(slower speed of leaf senescence) and ‘Centennial Seedless'(faster speed of leaf senescence) grown under protected and delayed conditions were used. The three treatments, replicated three times, were control(no supplemental lighting), red light and blue light. Chlorophyll content, net photosynthetic rate, and the ratio of F_v/F_m significantly increased in red light relative to the control. The opposite trend was observed in blue light in the early phase of leaf senescence. At later stages, physiological indexes were gradually higher than that of control, resulting in a delay in leaf senescence. Compared to the control, red and blue light both significantly increased the chlorophyll a/b ratio. Electron microscopy showed that blue light caused severe damage to the fine structure of chloroplasts at early stages of leaf senescence, but effects at later stages of leaf senescence became less severe compared to the control. The degradation of chloroplast ultrastructure was apparently delayed in red light throughout the experimental timeframe compared to other treatments. In this experiment, ‘Italia' showed higher chlorophyll content, net photosynthetic rate, ratios of F_v/F_m, chlorophyll a/b and better preserved chloroplast ultrastructure relative to ‘Centennial Seedless', resulting in a slower rate of leaf senescence. | WANG Shuai WANG Xiaodi SHI Xiangbin WANG Baoliang ZHENG Xiaocui WANG Haibo LIU Fengzhi | 2016 | Horticultural Plant Journal2016，2，2： | 10 |

| 8 | Sedimentary Characteristics of the Cretaceous in the Songliao Basin显示文摘The rupture of the lithosphere in Late Jurassic brought about the eruption of basaltic magma in the Songliao Basin. The evolution of the basin in Cretaceous progressed through six stages: pre-rift doming, extensional fracturing, fault subsidence, fault downwarping, downwarping and shringkage, resulting in the deposition of terrstrial facies nearly 10,000 m thick. There are different depositional sequences in these stages: the depositional period of the Early Cretaceous Shahezi and Yincheng Formations is the development stage of the down-faulted basin, forming a volcanic rock-alluvial fan-fan delta-lacustrine (intercalated with episodic turbidites)-swamp facies sequences; the period of the Early Cretaceous Dengluku Formation is the transformation stage of fault subsidence into fault downwarping of the basin, forming a sequence mainly of alluvial plain-lacustrine facies; the depositional period of the Early Cretaceous Quantou Formation-Late Cretaceous Nenjiang Formation is the downwarping stage of the basin, forming an alluvial plain-delta-lacustrine facies sequence; the period of the Late Cretaceous Sifangtai Formation-Mingshui Formation is the shringkage stage of the basin, forming again a sequence mainly of alluvial plain-alluvial fan and small relict lacustrine facies. These vertical depositional sequences fully display the sedimentary characteristics of a failed continental rift basin. Many facts indicate that the two large-scale lake invasions, synchronous with the global rise of sea level, which took place in the downwarping stage of the basin development, led to the connection between the lake and sea. | Liu Zhaojun, Wang Dongpo, Liu Li, Liu Wanzhu, Wang Pujun, Du Xiaodi and Yang Guang Changchun University of Earth Sciences, Changchun, Jilin Sun Sheping | 1993 | Acta Geologica Sinica(English Edition)1993，67，2： | 7 |
| 9 | The error source analysis of oil spill transport modeling: a case study显示文摘Numerical modeling is an important tool to study and predict the transport of oil spills.However,the accuracy of numerical models is not always good enough to provide reliable information for oil spill transport.It is necessary to analyze and identify major error sources for the models.A case study was conducted to analyze error sources of a three-dimensional oil spill model that was used operationally for oil spill forecasting in the National Marine Environmental Forecasting Center(NMEFC),the State Oceanic Administration,China.On June 4,2011,oil from sea bed spilled into seawater in Penglai 19–3 region,the largest offshore oil field of China,and polluted an area of thousands of square kilometers in the Bohai Sea.Satellite remote sensing images were collected to locate oil slicks.By performing a series of model sensitivity experiments with different wind and current forcings and comparing the model results with the satellite images,it was identified that the major errors of the long-term simulation for oil spill transport were from the wind fields,and the wind-induced surface currents.An inverse model was developed to estimate the temporal variability of emission intensity at the oil spill source,which revealed the importance of the accuracy in oil spill source emission time function. | LI Yan ZHU Jiang WANG Hui KUANG Xiaodi | 2013 | Acta Oceanologica Sinica2013，32，10： | 6 |
| 10 | The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability. | Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding | 2022 | Molecular Plant2022，15，5： | 6 |
| 11 | An Overview of Finite/Fixed-Time Control and Its Application in Engineering Systems显示文摘The finite/fixed-time stabilization and tracking control is currently a hot field in various systems since the faster convergence can be obtained. By contrast to the asymptotic stability,the finite-time stability possesses the better control performance and disturbance rejection property. Different from the finite-time stability, the fixed-time stability has a faster convergence speed and the upper bound of the settling time can be estimated. Moreover, the convergent time does not rely on the initial information.This work aims at presenting an overview of the finite/fixed-time stabilization and tracking control and its applications in engineering systems. Firstly, several fundamental definitions on the finite/fixed-time stability are recalled. Then, the research results on the finite/fixed-time stabilization and tracking control are reviewed in detail and categorized via diverse input signal structures and engineering applications. Finally, some challenging problems needed to be solved are presented. | Yang Liu Hongyi Li Zongyu Zuo Xiaodi Li Renquan Lu | 2022 | IEEE/CAA Journal of Automatica Sinica2022，9，12： | 6 |
| 12 | Oxidative Desulfurization of Fuel Oil at Room Temperature Catalyzed by Ordered Meso-macroporous HPW/SiO2显示文摘A serial of ordered meso-macroporous phosphotungstic acid(HPW) supported on SiO2 nanocomposites were successfully prepared by a homogeneous precipitation method, using monodispersed polystyrene(PS) microspheres and cationic surfactant as structure directing agent. These nanocomposites were used as catalysts for oxidative desulfurization(ODS) of model fuel. The materials were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), N2 adsorption-desorption isothrem, X-ray diffraction(XRD), and Fourier transform infrared spectra(FTIR). The characterization results suggested that the as-prepared material possessed ordered meso-macroporous architectures with Keggin type phosphotungstic acid dispersed homogeneously in SiO2 matrix. Under the selected reaction conditions, dibenzothiophene(DBT) in model fuel can be removed within 2 h at room temperature(30 ℃). In addition, only 1.2% of efficiency lose than the fresh catalyst even after 5 cycles. | 郭振冉 杜岳 雷家珩 ZHOU Lina DU Xiaodi | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，5： | 5 |
| 13 | Effect of Crosslink Structure of Bridge Polycarboxylate Superplasticizers on Dispersion Ability显示文摘Bridge polycarboxylate superplasticizers(PCs) with crosslink structure were synthesized by using polyethyleneglycol di-acrylate(PEGdA), replacing partial polyethyleneglycol mono-acrylate (PEGmA) as crosslinking agent. Structures of bridge PCs were analyzed by gel permeation chromatography, and dispersion ability was evaluated by cement paste dispersity variation on time and rheology test. The experimental results showed that, molecular weight(MW) of bridge PCs increased with increase of PEGdA proportion, and MW distribution curve changed from Gaussian to flat like, which meant notable increase of highly crosslinked copolymer. Bridge PCs led to decreased initial cement paste dispersity and better dispersity retention due to slow releasing. Further research showed that, PEGdA proportion had slight effect on polymerization degree of backbone, MW distribution of backbone deviated from Gaussian distribution and shoulder peaks appeared on distribution curve when PEGdA increased. | 毕耀 雷家珩 DU Xiaodi ZHANG Anfu | 2013 | Journal of Wuhan University of Technology(Materials Science)2013，28，2： | 5 |
| 14 | Gladius growth pattern and increment of jumbo squid(Dosidicus gigas)in the tropical Pacific Ocean显示文摘Gladius is an accepted hard tissue for determining the age,size-specific growth,and trophic dynamics of pelagic squid.However,little is known about the inter-and intra-stock variability of gladius growth pattern and increment deposition.In this study,the gladius growth patterns with somatic growth and gonad development were evaluated for two geographic stocks of the jumbo squid(Dosidicus gigas)in the tropical Pacific Ocean.The microstructure and periodicity of the gladius growth increments were also investigated.Results showed varied correlations between four gladius morphometric characteristics with dorsal mantle length,while growth in body weight almost followed a power model.Sexual gladius growth patterns occurred with gonad development,possibly due to different biological functions of these gladius parts and sex-specific energetic allocations.Gladius increments were observed formation in the stem and lateral plate and could be consistently enumerated.The daily periodicity of increment deposition,at least over 144 days old,was validated by comparing gladius increments with the ages obtained from the statoliths.The different oceanographic conditions between two areas likely influence the gladius growth and increment deposition and promote higher increment counts in squid from equatorial waters.Above all,these results provided new information on gladius microstructures and growth increment in different stocks of D.gigas and confirmed the use of this tissue for size-specific growth and age determination. | Yi Gong Yunkai Li Xinjun Chen Xiaodi Gao Ling Chen | 2018 | Aquaculture and Fisheries2018，3，4： | 4 |
| 15 | Silicon-coated fibrous network of carbon nanotube/iron towards stable and wideband electromagnetic wave absorption显示文摘Materials that can absorb electromagnetic(EM)wave have garnered increased attention in recent years due to their potential to mitigate the ever increasing environmental pollution by EM waves.Thanks to recent advances in micro/nanofabrication,a variety of magnetic metal-based EM absorbers have been reported.The design and synthesis of EM absorbers that exhibit efficient and wide-band absorption at small thicknesses,however,remains elusive.Here we report the design of fibrous nanostructures consisting of magnetic iron(Fe)nanoparticles and carbon nanotubes(CNTs),which exhibits a wide-band EM absorption(3.8 GHz)while maintain the thickness at 1.2 mm.In our work,we created a novel core-shell structure by immersing the highly fibrous CNT-Fe structure into solid-state silicon(SiO)matrix.Finally,the SiO-coated CNT-Fe structures exhibit good stability against air-induced oxidation and acid corrosion while maintaining high EM absorption.Overall,the results reported in this study present new avenues to absorb EM from ambient air.We believe that our work elevates the utility of EM absorbers to real-world applications such as anti-acid and oxidation ability. | Xiaodi Zhou He Han Yuchao Wang Cheng Zhang Hualiang Lv Zhichao Lou | 2022 | Journal of Materials Science & Technology2022，，26： | 4 |
| 16 | Chronostratigraphy and Stratigraphic Classification of the Cretaceous of the Songliao Basin显示文摘Isotopic ages of synsedimentary clay minerals were directly determined with the ultrasonicscattering-settlement separation-K-Ar dilution technique. The apparent age of black mudstoneis 123 Ma for the Quantou Formation, 111.9-89.0 Ma for the Qingshankou Formation and77.6-76.8 Ma for the upper part of the Nenjiang Formation. The Rb-Sr isochrone age of themuddy limestone-mudstone sequence of the lower part of the Nenjiang Formation is 81 Ma andthat of the muddy evaporite of the middle part of the Quantou Formation is 122.2 Ma. On thebasis of the above isotopic ages, the authors propose a modified scheme of stratigraphic classifi-cation of the Cretaceous of the Songliao basin. | Wang Pujun Du Xiaodi Wang Jun and Wang Dongpo 1)Geoenergy Department, Changchun University of Earth Sciences, Changchun, Jilin 2)Earth Sciences Department,Nanjing University,Nanjing,Jiangsu | 1996 | Acta Geologica Sinica(English Edition)1996，70，2： | 4 |
| 17 | Genome and transcriptome of Papaver somniferum Chinese landrace CHM indicates that massive genome expansion contributes to high benzylisoquinoline alkaloid biosynthesis显示文摘Opium poppy(Papaver somniferum)is a source of morphine,codeine,and semisynthetic derivatives,including oxycodone and naltrexone.Here,we report the de novo assembly and genomic analysis of P.somniferum traditional landrace‘Chinese Herbal Medicine’.Variations between the 2.62 Gb CHM genome and that of the previously sequenced high noscapine 1(HN1)variety were also explored.Among 79,668 protein-coding genes,we functionally annotated 88.9%,compared to 68.8%reported in the HN1 genome.Gene family and 4DTv comparative analyses with three other Papaveraceae species revealed that opium poppy underwent two whole-genome duplication(WGD)events.The first of these,in ancestral Ranunculales,expanded gene families related to characteristic secondary metabolite production and disease resistance.The more recent species-specific WGD mediated by transposable elements resulted in massive genome expansion.Genes carrying structural variations and large-effect variants associated with agronomically different phenotypes between CHM and HN1 that were identified through our transcriptomic comparison of multiple organs and developmental stages can enable the development of new varieties.These genomic and transcriptomic analyses will provide a valuable resource that informs future basic and agricultural studies of the opium poppy. | Li Pei Baishi Wang Jian Ye Xiaodi Hu Lihong Fu Kui Li Zhiyu Ni Zhenlong Wang Yujie Wei Luye Shi Ying Zhang Xue Bai Mengwan Jiang Shuhui Wang Chunling Ma Shujin Li Kaihui Liu Wanshui Li Bin Cong | 2021 | Horticulture Research2021，8，1： | 4 |
| 18 | A Superaerophobic Bimetallic Selenides Heterostructure for Efficient Industrial-Level Oxygen Evolution at Ultra-High Current Densities显示文摘Cost-effective and stable electrocatalysts with ultra-high current densities for electrochemical oxygen evolution reaction(OER)are critical to the energy crisis and environmental pollution.Herein,we report a superaerophobic three dimensional(3D)heterostructured nanowrinkles of bimetallic selenides consisting of crystalline NiSe2 and NiFe2Se4 grown on NiFe alloy(NiSe2/NiFe2Se4@NiFe)prepared by a thermal selenization procedure.In this unique 3D heterostructure,numerous nanowrinkles of NiSe2/NiFe2Se4 hybrid with a thickness of ~100 nm are grown on NiFe alloy in a uniform manner.Profiting by the large active surface area and high electronic conductivity,the superaerophobic NiSe2/NiFe2Se4@NiFe heterostructure exhibits excellent electrocatalytic activity and durability towards OER in alkaline media,outputting the low potentials of 1.53 and 1.54 V to achieve ultra-high current densities of 500 and 1000 mA cm^−2,respectively,which is among the most active Ni/Fe-based selenides,and even superior to the benchmark Ir/C catalyst.The in-situ derived FeOOH and NiOOH species from NiSe2/NiFe2Se4@NiFe are deemed to be efficient active sites for OER. | Jiaxin Yuan Xiaodi Cheng Hanqing Wang Chaojun Lei Sameer Pardiwala Bin Yang Zhongjian Li Qinghua Zhang Lecheng Lei Shaobin Wang Yang Hou | 2020 | Nano-Micro Letters2020，12，8： | 4 |
| 19 | Preparation of Polycarboxylate-based Superplasticizer and Its Effects on Zeta Potential and Rheological Property of Cement Paste显示文摘A series of polycarboxylate-based superplasticizers(PCs) with different structures were synthesized and the effects of chemical structure on zeta potential and rheological property of cement paste were studied. Residual monomers in each sample of PCs were quantitatively determined. The property of the polymers in cement was tested by micro-electrophoresis apparatus and R/S rheometer. Results showed that the zeta potential and its rheological properties are related with the side-chain length and density of PCs. The PCs having shorter side chain and lower side chain density exhibit higher anionic charge density, thus resulting in higher zeta potential. The effect of side chain density on zeta potential is more notable compared with that of side-chain length, and thus affecting the initial shear yield stress and apparent viscosity of the cement paste. In addition, although increasing the side chain length will result in reduction of the anionic charge density, the steric hindrance effect is obvious, which can effectively improve the dispersion of the cement particles, and reduce the viscosity and shear yield stress of slurry. | 刘明 雷家珩 BI Yao DU Xiaodi ZHAO Qinglin ZHANG Xuqing | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，5： | 3 |
| 20 | Biomass-Derived Carbon Heterostructures Enable Environmentally Adaptive Wideband Electromagnetic Wave Absorbers显示文摘Although advances in wireless technologies such as miniature and wearable electronics have improved the quality of our lives,the ubiquitous use of electronics comes at the expense of increased exposure to electromagnetic(EM)radiation.Up to date,extensive efforts have been made to develop high-performance EM absorbers based on synthetic materials.However,the design of an EM absorber with both exceptional EM dissipation ability and good environmental adaptability remains a substantial challenge.Here,we report the design of a class of carbon heterostructures via hierarchical assembly of graphitized lignocellulose derived from bamboo.Specifically,the assemblies of nanofibers and nanosheets behave as a nanometer-sized antenna,which results in an enhancement of the conductive loss.In addition,we show that the composition of cellulose and lignin in the precursor significantly influences the shape of the assembly and the formation of covalent bonds,which affect the dielectric response-ability and the surface hydrophobicity(the apparent contact angle of water can reach 135°).Finally,we demonstrate that the obtained carbon heterostructure maintains its wideband EM absorption with an effective absorption frequency ranging from 12.5 to 16.7 GHz under conditions that simulate the real-world environment,including exposure to rainwater with slightly acidic/alkaline pH values.Overall,the advances reported in this work provide new design principles for the synthesis of high-performance EM absorbers that can find practical applications in real-world environments. | Zhichao Lou Qiuyi Wang Ufuoma IKara Rajdeep SMamtani Xiaodi Zhou Huiyang Bian Zhihong Yang Yanjun Li Hualiang Lv Solomon Adera Xiaoguang Wang | 2022 | Nano-Micro Letters2022，14，1： | 3 |
